Charging your headphones

Note: This product cannot be used while charging.

1. Open the door on the right side of the neckband
2. Connect a USB cable from the product to a USB charger. The battery light blinks amber while charging and glows solid green when charged.
   
   Typically, the battery will fully charge in about three hours; this varies depending on the charge level and the charger used. In some cases, it can take up to 10 hours to fully charge.

CAUTION: Use this product only with an agency-approved power supply that meets local regulatory requirements (i.e. UL, CSA, VDE, CCC).

Lithium batteries have a built-in auto-off feature when a full charge is reached to prevent the battery from being overcharged. Even while still plugged in, the battery level will have to drop below a certain point to trigger the charging again.
